This article explains what sealing rings are and their critical role across industries. It covers common types (O-rings, V-rings, X-rings, piston rings), key materials (NBR, FKM, EPDM, PU, PTFE) and their temperature/chemical limits, and major application sectors including automotive, construction machinery, and hydraulic systems. A practical selection guide helps readers match sealing rings to pressure, temperature, and media conditions. MingYu Sealing Technology, an IATF 16949 certified manufacturer with nearly 30 years of experience, offers custom sealing rings and engineering support for demanding industrial applications.
This article provides a comprehensive comparison of PTFE and polyurethane piston seals for high pressure applications. It examines key performance factors including friction coefficient (PTFE: 0.04; PU: up to 0.9), temperature limits (PTFE: -200°C to +260°C; PU: -30°C to +100°C), extrusion resistance (PU handles 400 bar+ without backup rings), and chemical compatibility. The guide helps engineers select the optimal material based on operating conditions, speed requirements, and environmental factors. MingYu Sealing Technology offers both PTFE and polyurethane piston seals, including custom rubber seals, Custom Wiper Seals FC, and custom dust cover components, backed by IATF 16949 and ISO 9001 certifications.
This guide answers the question "What materials are commonly used for piston rod seals?" by detailing five primary materials: NBR, FKM, Polyurethane, PTFE, and HNBR. It covers their temperature ranges, chemical compatibility, mechanical properties, and typical applications. The article also provides a step-by-step selection process, common failure mode prevention tips, and a material comparison table. MingYu Sealing Technology, an experienced rod seals manufacturer with IATF 16949 certification, offers engineering support to help you choose the optimal material for your specific hydraulic or pneumatic system.
